SUPPORT FOR ELECTRIC MACHINES.

Application filed August 30, 1920. Serial No. 407,070.

T 0 all w/aom 2' 23 may concern:

Be it known that I, HENRY E. Bononu, a citizen of the United States, residing at Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in a Support for Elec trio Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

This invention relates in particular to a support for electric machines, said'support being peculiarly adaptable for use with internal combustion engines, although it is also useful in other relations.

In order to understand the object of this invention it must be borne in mind that there is no standard practice in automotive engineering in the positioning of the electrical machinery with respect to the positionof the.

engine. It is optional with the different designers of automotive vehicles to place,

for example, the generator either on the right hand or the left hand side of the combustion engine. I I

It is an object of my invention to provide a support adaptable to either type of mounting. 7

It is a further object of my invention to provide means readily accessible from either side of the engine for the loosening of the retaining means of the generatoror other electrical machine. J I

It is a further object of my invention to make the electrical machine support as small and compact as possible and to so form the support as to utilize as little material as is consistent with the strength of material required.

In the drawings, Figure 1 is an end view of my support showing a generator secured in position thereon.

Figure 2 is a bottom plan-view of my support.

agonal reinforcing ribs 3 intersecting in the Figure 3 is a side view of my support center of said rectangle to form a hub or central portion 4; At each of the corners of therectangular block there is provided a hole 5 preferably threaded as is shown by dotted line 6 so that the base may be fas tened to the frame of the engine by bolts or other suitable securing means. Projecting from one side of the rectangular frame and preferably integral therewith is a flange 7 provided with two apertures 8 symmetrically spaced with reference to aline passing through the hub and perpendicular to the adjacent wall of the rectangular structure. In the opposite wall are tapped three holes 9, 10 and 11 of which the intermediate hole is on the imaginary linehereinbefore mentioned, while the holes 9 and 11 are disposed at equal distances from said line. The hub portion 4 of the base is drilled and, a centerin pin 12 is driven into the same, although it is understood that the pin may be threaded thereinto or cast integra l withthe base. The upper portion of the base is rounded as at 13 for the snug reception of the generator 14 that may be mounted thereon. vided with an aperture to accommodate the centering pin 12 so that the generator may occupy the same relative position whichever way it sits on the base, although it is, of

course, apparent that the pin may be mount-' end of the strap member 15 is bent back upon itself as at 16 and riveted together as at 17 to grip a pivot pin 19- as at 18 mounted in that end of the strap member.

Pivotally mounted on said pin is a bolt member 20 provided with a smooth shank 21 adapted to be passed through one of the apertures 8 and a nut 22 is provided to tighten down the strap member after the bolt has been passed through the aperture although, of course, the nut may be replaced. by a wing nut.

In use, if the electric machine is to be mounted on the left hand side of the internal combustion engine as in Figure 4 the strap member 15 is secured to the base 1 by means of two screws 23 and 24 and lock washers This generator is pro 25 and 26. The base is then mounted on and fastened to the engine frame. The electric machine is then centered on the frame by means of the centering pin 12 and the strap 15is thendrawn down around the machine by passing the shank 21 of the bolt 20 through the appropriate hole 8 in'the flange 7 and tightening the nut 22 thereon. A lock washer 27 is inserted between the flange and the nut to prevent the nut from loosenmg.

It is to be understood that electricmachines of the type suitable for internal com bustion engines are generally provided with a terminal such as 28 which would interfere with the placing of a strap member around the central portion of the machine without either unduly weakening the strap member as by cutting recesses therein orrendering the same inflexible as by making the same narrow and thick. Furthermore because of the lack of space on a motor vehicle, it is not desirable to provide two flanges so that a bolt 22 may be accessibly provided for each side of thestrap member.

If-it is desired to use the base on the opposite side of the engine, the generator is.

reversed on the base and the strap member is shifted in' alignment with the other pair of screw retaining means so as to avoid the terminal 28 and fastened in lace by means of the same screws by mere y shifting one of them from hole 11 to hole 9, while the bolt 20 is passed through the other aperture 8 in the flange 7 With apphcants invention it may be seen that the one base may be used on either side of the engine, that it may fit compactly into the frame work of the same and yet the machine supported thereon is readily removable since in either position of the base, the

bolt and nut are readily accessible.

It will be'clearly apparent that numerous changes and alterations may be made in the detalls of various parts of my invention without departing from the spirit of my invention or the scope of the appended claims.

said frame in any one of a plurality of positions.

2. A support comprising a frame, intersecting ribs joining the corners of said frame, a centering device at the intersection of said ribs, a strap member for said frame and a plurality of means on each side of the centering device and symmetrically disposed with respect thereto for securing said strap member to said frame in any one of a plurality ofpositions.

3. A metallic support comprising a frame having a plurality of strap fastening means on one side thereof, a strap member for said frame having one end held thereto by said strap retaining means, a centrall located centering device on the support si e of said frame, a flange on the side of the frame opposite said strap fastening means and having holes therein, said strap retaining means and said flange holes being symmetrically disposed with respect to said centering device for the purpose described, and means including a bolt passing through one of said flange holes for fastening the free'end of said strap to the flange.

In testimony whereof, I afiix my signature.
